一.最近一直在忙於開發公司的新的項目和搭建公司的框架，也好久沒有寫博客了。對於RaidDevelopmentFramework 我有著自己的見解在應用到實際的框架中確實挺好用的，但是還是存在一部分的問題。這個需要後期進行不斷的完善以及修改。最近一段時間對於這個WebApi 我又進行重新的研究和學習。
ASP.NET Web API是用於構建可以從任何客戶機訪問（包括瀏覽器和移動設備）的HTTP服務的框架。 它是一種基於.NET Framework構建RESTFUL應用程序的理想平臺。
二.那麽WebApi 如何在傳統的應用程序中進行使用和結合到.NET FrameWork 來進行使用。
三.ASP.NET Web API特性
-
Web API 是一個構建基於restful服務的理想平臺。
-
Web API 是基於Asp.Net,支持ASP.Net 請求/響應管道
-
Web API 有良好的路由機制。
-
Web API 支持不同格式的響應數據，內置支持JSON、XML BSON格式。
-
Web API 可以部署非常方便。
-
Web API框架包括新的HttpClient，他可以與Web API服務器通信。HttpClient可以在ASP.Net MVC服務器端,Windows Form應用程序,控制臺應用程序或其他應用程序中使用。
四. 關於
ASP.NET Web API版本
| web api版本 |
支持的.net framework版本 | 對應的MVC版本 | 支持的VS版本 |
| Web API 1.0 | .NET Framework 4.0 | ASP.NET MVC 4 | VS 2010 |
| Web API 2.0 | .NET Framework 4.5 | ASP.NET MVC 5 | VS 2012，VS 2013 |
ASP.NET Web API VS WCF
| web api | wcf |
| 開源，支持.net framework | 支持.net framework |
| 只支持HTT通信協議 | 支持HTTP，TCP，UDP以及自定義通信協議等 |
| 良好的路由機制來匹配url與對應接口 | 基於Attribute來匹配 |
| 使用類似於Asp.net MVC的路由規則和Controller模型 | 使用Service，契約等 |
| 不支持可靠的消息傳遞和事務。 | 支持可靠的消息傳遞和事務。 |
| 可以使用HttpConfiguration 來配置Web Api，不一定需要web.config配置 | 使用web.config和Attribute來配置一個服務 |
| 適合構建RESTful服務。 | 支持構建RESTful服務但有局限性 |
五. 下面通過進行對於CRUD 的方法使用來進行說明。
1 #region 使用客戶端進行調用WebApi來進行實現 2 #endregion 3 using System; 4 using System.Collections.Generic; 5 using System.Linq; 6 using System.Text; 7 using System.Threading.Tasks; 8 using System.Web.Http; 9 using System.Web.Http.Hosting;
